If A and B are two disjoint sets, then `n(AuuB)` is equal to `n(A)+n(B)` b. `n(A)+n(B)-n(AnnB)` c. `n(A)+n(B)+n(AnnB)` d. `n(A)n(B)`

If A and B are two disjoint sets, then n(AuB) is equal to a. n(A)+n(B) b. n(A)+n(B)-n(AnB) c. n(A)+n(B)+n(AnB) d. n(A)n(B)

If A and B are two disjoint sets,then n(A uu B) is equal to n(A)+n(B) b.n(A)+n(B)-n(A nn B) c.n(A)+n(B)+n(A nn B) d.n(A)n(B)

If Aa n dB are two sets, then (A-B)uu(AnnB) is equal to (a) AuuB (b) AnnB (c) A (d) B

If A and B are two finite sets,then prove that n(A uu B)=n(A)+n(B)-n(AnnB)

If set A and B are disjoint sets and n(A) = 6, n(B) = 5, then n(AuuB) =

If A and B are two disjoint sets and n (A) = 15 and n (B) = 10 find n (AcupB),N(AcapB).

Establish that: n(A uu B)=n(A)+n(B)-n(AnnB)

If A and B are two sets such that n(AuuB)=50 ,\ n(A)=20\ a n d\ n(B)=32 ,\ f i n d\ n(AnnB)dot

If A and B are two sets such that n(AuuB)=50 ,n(A)=28,n(B)=32,then find n(AnnB) .

If A and B are two non empty sets the prove the following1.n(AuuB)=n(A)+n(B)-n(AnnB) ." " 2. nAuuBuuC)=n(A)+n(B)+n(C)-n(AnnB)-n(BnnC)-n(Cnna)+n(AnnBnnC)
